摘要

Device for the introduction of calcium treatment means in the manufacture of steel with increased toughness characteristics, characterized in that for the introduction of finely granulated calcium treatment means in steel melts, it is constituted by a gas lift battery, a deposit for the finely granulated treatment medium, a suspension and an immersion lance, arranged at the bottom of the tank with a pipe for the introduction of the support gas and a slurry for the suspension, which releases through a transport conduit for the suspension stream is in communication with the suspension outlet and it is anticipated that the transport conduit has a mixing chamber that allows a pressurized gas inlet into the suspension stream, and because the mixing chamber through a conduit secondary with a regulating valve is in communication with the head of the dep site, while battery lift gas is coupled to the bulb socket the introduction of lift gas on the suspensador.
